Hello,
The old FireWire wiki was outdated because the old drive stack was used and it was divided over three articles so I started from scratch by using information of old articles
NEW: https://help.ubuntu.com/community/FireWire (group of articles / please click on URLs in article) OLD1: https://help.ubuntu.com/community/FireWire/oldPages/Firewire01 OLD2: https://help.ubuntu.com/community/FireWire/oldPages/Firewire02 OLD3: https://help.ubuntu.com/community/FireWire/oldPages/Firewire03
Please check for any mistakes and please give suggestions for additions to the articles or if something is missing.
Thank you, Dooitze
